Jarring

[Myron Tay]

When do you start to jar the juveniles?

[Chris Yew]

HI Myron,

So you're back again! I start to jar as early as 1.5 mths if they are growing fast. It all depends on each individual spawn and fish. No hard and fast rule. If you spot a good one, juz jar it before it got ribbed off. LOL! If you have plenty of plants inside the growing up thank, then there's no need to jar them too early (2 to 3mths also can).

Thanks Chris!

You are always so helpful. Thanks for the advice.

This is the spawn from the father who was an egg-eater. My third try and I have got a grand total of....11 fries coming to one month old.

Ah well, at least better than the spawning efforts of my group in the office. All we have to show today for all our spawning efforts on live-bearing fish is one miserable platy. :(

About 2 months to 3 months. Anything beyond that will mean high number of nibbed fins.

I tried once at 4 months before I started jarring ... lots of casualties ... even when the tank is really large. (5ft)

My advices ... Get the good ones out as soon as they are detected.

With Best Regards,
Samuel Phan

There is no hard n fast rule how old to start jarring. Actually teh rule in our case [ hobbyist] is how many hours you have to spare on yr fishes...ha! ...not so much of whether they are aggressive or not. Fresh water triggers agrression. So try not change the water once they start to become little bulldogs. having said the water must be still kept biologically clean.

I only isolated the potential ones, teh rest that dont show much potential are left in the tank. If after 2.5 mths they still dont look to improve///too bad.....they will have to wait for their reincarnation!

To share what i learnt from a friend, he told me that when fishes are raised in a pond, there will be no fighting and nipping of fins. However, if something or someone like a frog causes a stir in the pond by dashing about in the pond, the fishes will start to have behavioral changes. For example, the fishes will start to bite each other and not living as harmoniously together like before. Then he proved to point to me. He brought up a spawn of fishes which are 5 weeks old and quite big already. None of the fishes have any nips on their finnage, he transferred the fishes to a 4 foot tank. So we sat down there looking and chatting. After an hour or so, the fishes started to flare at each other which did not happen during the last hour. And after 30 minutes, the fishes started full flaring and biting each other. After 2-3hours, after picking up some fishes, the remaining ones in the tank already had some serious nips on the fins.

Can I safely assume the 5 week old spawn was living harmoniously in a pond prior to being released into the 4 feet tank? Is there are change in water clarity? Is there a change in the space per fish in the tank vis-a-vis the pond?

[Sebas]

Yes, u can safely assume that the 5 week old spawn was living harmniously in a pond prior to a transfer to a 4 feet tank. I saw it myself. And Myron, of cuz there is a change in the space per fish ratio. Pond to tank! Whether they can see each other or not, i am not sure, i didnt put my head into the pond. haha, well, i know whatyou are thinking, it may also be true. He gave me another instance, he had a spawn of potential HMs. When he picked some out, they were fine, no nips. But one day, there was a downpour. A frog accidentally jumped into the pond and messed the floor of the pond by dashing about. So the next day, when he took out the fries, all of them were badly tattered.

if i may include.. this occurs when one is netting out fishes out of the community tank as well. that's why it's good practice to always lure the fish you want using food, and slowly net him/her out of the water. biting will eventually occur usually after water changes (hence, experienced breeders, in my opinion, does not like to change water. therefore, use huge water volume)and when one accidentally scares the fishes (either through lighting or knocks on the tank). in short, any form of noise/physical disturbance will disrupt the equilibrium (already established by all the fishes in the tank), resulting in fish mis-orientation and subsequently, nipping or re-nipping. i've not encounter non-nipping cases at my friend's place or at home as well through the earlier instances i mentioned earlier

i would like to think that this is very difficult problem to avoid. perhaps, U. Derrick who has aplenty space, serenity and peace in his vicinity can provide some insights into this matter?

[Lyon Goh]

Uncle Derrick keeps the father of each spawn with the fry. Surprisingly, no Fry got nipped! Maybe 1 or 2 but even HM finnages were not destroyed. So I believe that with the father inside, the fry fights lesser

[derrick kuah]

Yes Lyon ,
Will bring one steel overhms tomorrow,thought it a female, never jar the "buggy" till i wash the tank , full of females, last week.
Even with 100+ fries in 2 feet tank, if you keep the perimeters to minimum changes, you should be able to keep them(no fighting) till 16 weeks or more(for irres), not for red don,t know why.
Alway catch the fishes from the surface of water , do not stir the water. That is how i can keep them in the tank for loong period.For water changes , i only suck out the dirts from the bottom with a hose then top up with new water(aged), no more then 1/3 the volume.Maybe cos i alway have the father with them.I have a turquios spawn , about 16 weeks, started to jar two days ago. Only have minimum nip on finnages, will bring two tomorrow.
see you guys there ... good luck
thanks and regads derrick++

SEbas,
Yes , your friend is right.Try going to any fish farm and try catching thier fishes from the tank(cement) in the afternoon. Most seasoned farmer will not allow you to do it.Not only bettas, others fishes will also have "perimeters" problems if you stirred the water from the bottom???? what to know the reason why????

Remember your secience lesson in school.Espcially cement tank.Cos the temp at the bottom and the water at the top(water surface) is different. If you stirred it , you will caused a imediate changed in temp , most fishes can,t take it. For bettas , which is very hardy, most will not has problem, but cos of the changes, they have to reestablish thier area.
Hope its the right infors and didn,t make a fool out of myself.My only 2 cts worth.
thanks and regrads derrick++
Interesting theory, Derrick. Thanks for sharing.
